A: So have you read this book?
B: What book?
A: It's about these two kings, one convinces his people to be his slaves, but the people are convinced that being a slave is the best thing for them.
B: Really?
A: Yeah, and the other king gives his people freedom to do as they want.
B: Cool.
A: Thing is, the kingdoms are really close to each other to the point the borders are in dispute and the two peoples are forced to intermingle.
B: How does that work?
A: Violently. The slave kings people always try to enslave the free kingdom's people, and when they can't they are willing to go as far as to kill them. The people of the free kingdom try to free those enslaved however they never even try to hurt those enslaved.
B: Ok so the slaves are dumb and violent, how's the book end?
A: I don't know yet, christian history is still being written.
B: What? (Sounding suspicious and wary.)
A: Would you like to be free from your slavery?
B: I'm not a slave.
A: Your not going to spend eternity in servitude?
B: Oh f*ck you! I should kick your a*s! (Storms off)

3 months later

B: Hey, f*ck you half my family won't talk to me any more!
A: How is that my fault?
B: I'm not a slave any more. (smiles)
A: Freedom is hard isn't it?
B: Yeah, but its worth it.
